d. None of these examples are correct.
Answers
Answer:
c. founder effect
Explanation:
The founder effect occurs when there is a loss or reduction of genetic variation when a new population is produced or established by a few number of individuals from a large population. In other words, a new colony is formed from a large population. This could result to differences in phenotype ad genotype of the new population from the original population.
The gene pool of the new population is also affected. The small group of squirrels that separated from the the large population during the flood to form a new population, is an example of founder effect.

Threonine contains two functionalgroups: an amino group (-) and a hydroxyl group (-OH).
These functionalgroups are responsible for the molecule's properties and reactivity. The amino group is part of the amino acid structure, while the hydroxyl group is characteristic of alcohols.
The carboxyl group (-COOH) is another functionalgroup present in threonine. It is acidic in nature and can donate a proton, making threonine capable of acting as a weak acid.
The hydroxyl group (-OH) attached to the side chain of threonine is an alcohol functional group. It provides threonine with unique chemical properties.
Thus, threonine contains two distinct functional groups: an amino group (-) and a hydroxyl group (-OH).

An experimental pharmaceutical is typically approved after it passes 4 phase of clinical trials.
What is clinical trial ?
Clinical trials are combination of new research, studies and experiments performed in people to evaluate the effectiveness of new experiment on human health.
It consists of main 4 phases.
Phase 4 clinical trial is also known as " Post-Approval Research and Monitoring ". It is the final stage of trial for any pharmaceutical product, drug or device. This trial study about the side effects, real life scenarios, long-term risks and benefits of particular pharmaceutical product which were not seen in the early trials.
So we can sayan experimental pharmaceutical can be approved when it passes 4 phases of clinical trials.

The anatomical terms are used to define the anatomical positions. The LLQ (Left lower quadrant) is located inferior to the LUQ (left upper quadrant). Thus, option e is correct.
What are anatomical terms?
Anatomical terms are used to define the exact position and location of the organs and the structures of the body in reference to each other. They are the directional terms that provide the details of the direction an organ is situated at.
The directional anatomical terms include superior, inferior, posterior, anterior, distal, proximal, caudal, occipital, peripheral, central, etc. The LLQ (Left lower quadrant) is the abdominal section that is located below the LUQ (left upper quadrant).
The anatomical term inferior is used to show the structure that lies below the reference organ. On the other hand, the superior shows above, the posterior shows behind, the anterior shows the front area, and the distal shows structures located further away from the origin.
Therefore, option e. the left lower quadrant is inferior to the left upper quadrant.

Final answer:
In terms of human anatomy, the Left Lower Quadrant (LLQ) is considered to be inferior to the Left Upper Quadrant (LUQ). This refers to the LLQ's position being lower or below the LUQ.
Explanation:
In anatomical terminology, the Left Lower Quadrant (LLQ) is inferior to the Left Upper Quadrant (LUQ). The human abdomen is divided into four quadrants by two imaginary lines crossing each other at the naval: one vertical and one horizontal. The LUQ is the area on the left side above this intersection, whereas the LLQ is the area below. So in the context of positions and directional terms in human anatomy, 'inferior' means 'below' or 'lower than'.
